Things I like about the babies, toddlers, and preschoolers I meet at work:
When you can sort of see what parts of their face they will still have as a grownup.
When you can see how they resemble their parents.
When they concentrate really hard, but because they are babies, it is often on something fairly simple like standing or eating a cracker.
When they start picking out their own clothing and exhibit a wild baby style.
That they want to try things out, even if those things are a little bit out of their ability.
When they are just getting comfortable with locomotion and have to stomp or lunge everywhere.
When they are just being casual, eating a bagel or some Cheerios.
That baby accent, before they can pronounce all the sounds very well.
